DUMPlNG-CAR.

FICATION forming' part of Letters Patent No. 777,020, dated December 6, 1904.

Application iled April 5, 1904. Serial No. 201,724. (No model.)

7G/1, it may concern.- 1,:nown that I, JOSEPH D. HAMPTON, residing at Hazleton, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Dumping-Cars, of which the following is a specification. My invention relates to the class of dump ing-cars, and more particularly to those cars adapted for use Ain coal and other mines, and it more particularly seeks to provide a simple and eecti ve dumping-car which can be simply and economically constructed and which will readily serve its intended purposes.

Generically the invention embodies a skeleton car, including fiXedly-held sides and ends and a movable platform or false bottom carrying a pusher or false end at one end and which under predetermined conditions can be brought into operative connection with the drive-wheel axle whereby to move the bottom in an endwise direction to dump the contents fof the car. g The invention also embodies an automatically-released gate adapted to be unlocked as f the bottom is moved endwise to dump or eject all the contents of the car and to be again locked when the bottomis returned to its initial position.

With other objects in view, which will be hereinafter fully apparent, the invention consists in certain novel construction and combination of parts, all of which will be first described in detail and then specifically pointed out in the appended claims, reference being had to the accompanyingdrawings, in which- Figure 1 is a perspective view of a car constructed in accordance with my invention. Fig. 2 is an inverted perspective view thereof. Fig. 3 is a longitudinal sectional View taken on the line 3 3 of Fig. 2. Fig. 4 is a similar view, the parts being in their dumping position. Fig. 5 is a cross-section on the line 5 5 of Fig. 2. Fig. 6 is a detail perspective view of the false platform looking from beneath the same.

Referring now to the accompanying drawings, in which like numerals and letters of reference indicate like parts in all the figures, the car C comprises the longitudinal and transverse bottom cross-beams 1 2, to which the uprights 1 2 are secured, and the longitudinal and transverse top cross-beams 3 4, secured to the uprights 1 2a. 5 5 designate the sides of the car, and 6 indicates the iXedly-held end,

'all of which are secured to the uprights la 2'L and the cross-beams in any approved manner.

4The said uprights may be braced by the diagonal braces 1. 1b, as shown in Fig. 1.

Secured to the transverse beams 2 2 is a pair of II-Sha'ped guide-beams 7 7 which coper-l Patented December 6, 1904.

shafts 9 9 each carrying a sprocket-wheel 9b 9", with which the endless chain 9 cooperates, and

has secured thereto a cross-piece 11, which carries a pair of angle-braces 11l 11d, coperating with the gate 15, which gate is hingedly secured to the cross-beam 4C. The angle-braces 11d 11d serve to hold the gate locked to its closed position when the parts are in their normal position, as shown in Fig. 1.

The T-shaped rack-carrying member 10 consists of two parts 10 10", one of which, 11, is fixedl y secured to the bottom l1 by the bolts w or otherwise, While the part 10b is connected to the part 10L by the'hinges 10c 10 Vfor a purpose presently to appear, and the said member 10a has a longitudinal groove 10l in its under side which is adapted to receive the rack 12, which is in three parts, two of which, 12

11x llxdesignate stops on the bottom 11 to limit the endwise movement thereof.

Mounted in bearings 13 13 on the longitudinal beams 2 2 and in a bearing 13u on the guide-beams? is a shaft 14, having levers 14 at each extremity thereof, which project upwardly alongside the car, the said shaft 14 being located about midway the ends of the car, This shaft 14 also carries a crank-arm 14h between the guide-beams T and the beam 2, the said crank-arm 14 being' joined to the crankarms 16b of a shaft 16 by means of the rod 14. The shaft 16 is mounted in bearings 16L 16JL on the guide-beams 7 7 and in advance of the gear 9d, and the said shaft is provided with a n-shaped portion 16c for cooperating With the rack portion 12"L to hold it out of engagement with the gear 9d when the parts are in their normal positions. A stop or catch s is provided on the car sides to hold the lever 14St in such a position as to maintain the nshaped portion 16c in engagement with the rack portion 12 when the parts are in their normal position.

If necessary, I may cover the bottom 11, together with its pusher portion 11, with a metal sheathing 20, and I may also cover the inner sides and end walls 5 6 with a like sheathing 21, if found desirable in practice.

So far as described the operation of my invention can be best explained as follows: When the parts are in the position shown in Figs. 1 and 2, the car is ready to receive its load, the rack 12being held out of engagement with the gear 9 by the portions 16c of the shaft 16 to allow of a free movement of the car, the lever 14 beingin engagement with the stop At this time the end-gate is closed and the bottom is in position with its false end 0r bottom against the iixed end or' thel carframe. The car after it has been loaded is moved from place to place, as desired, by any suitable motor power, which may be the ordinary mule team, as used with the cars when in mines. IV hen the car arrives at the place where it is desired to unload, the attendant releases the lever 14", which then permits the spring 12l to move and hold the rack portion in engagement with the gear Ql. The car is then moved slightly forward, causing the gear 9d to bring the bottom forward, as shown in Fig. 3, thereby releasing the end-gate and permitting the pusher and the bottom to carry the material contained within the car out from between the car sides. As the bottom reaches the limit of its endwise movement the hinged jointg/ of the member 10 will be in alinement with the edge s of the cut-away portion e' ot' the cross-beam 2, which cut-away portion is slightly wider than the vertical portion of the T-shaped member 10 to allow the bottom to tilt, as shown in Fig. 4. Theh( 1()x of the member 10 which grooves of the longitudinal g gage the edges z2 of the beam 2. This tipping or tilting' of the permit the contents thereof to sli\ come dumped. After the car has b or unloaded in the manner just t is only necessary to move it in the rection, when the gear 9d will ag the bottom t'o its normal position, a the rack is again disengaged fron by bringing the said lever into el with the stop s, it being understc the bottom returns to its normal po: the car has been dumped the hang gate will be again engaged by the angler. L

tion on the cross-piece attached to the bottom` and lock the same from opening.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the advantages and complete operation o'f my invention will be readily understood by those skilled in the art to which it appertains, and I desire it clearly understood that slight changes in the detailed construction and arrangement of parts may be made without departing from the scope of the invention and the appended claims.

I am aware that dumping-cars have been heretofore provided in which a tiXedly-held hopper is mounted upon a car-truck and with a removable bottom, and I am also aware that dumping cars having removable sides and tilting bodies have been provided, and I thereore do not broadly claim such construction;
